Problems solved by technology

[0005] ①. Since the current tooling only adopts both ends to support, the middle skin is easily deformed during hole making, which increases the error of hole making
②. Due to the cover of the pressing plate, the coverage rate of the hole making will not reach 100%.
③. Hole making and riveting cannot be carried out on the tooling at the same time
Therefore, there are many problems in the current tooling, which affect work efficiency and quality safety.

Abstract

The invention provides a long truss skin tooling structure, comprising: a workpiece fixing device, a workpiece positioning device, a fixing beam and a frame body, the fixing beam is vertically arranged on the frame body; the workpiece fixing device includes: a clamp part , a bracket part and a suction cup part, the bracket part is arranged on the fixed beam, and the bracket part is provided with a protruding support platform; the clamp part and the suction cup part are both arranged on the bracket part, and the lower pressing end of the clamp part can touch the support platform The upper end surface of the suction cup part is in the same direction as the outer end surface of the support platform; the workpiece positioning device is arranged on the side beam and / or cross beam of the frame, and is used for positioning the long stringer and the skin. Through the long stringer skin tooling structure provided by the embodiment of the present invention, two acting forces in opposite directions can be used to make the long stringer and the skin closely fit, the skin and the long stringer are not easily deformed, and the hole making operation is convenient. The hole coverage can be improved.

Description

technical field [0001] The invention relates to the technical field of workpiece assembly, in particular to a long truss skin tooling structure. Background technique [0002] Large panels are widely used in structures such as wings and fuselages. Typically, large siding consists of skin and stringer structures. The girder and the skin are fixed by riveting, so it is very important to be able to complete the hole riveting work accurately, quickly and with high quality. [0003] At present, mechanical wood clamping tooling is mostly used for the hole making of aircraft long trusses. When working, first install the stringer to the calibrated position, and at the same time fix and lock both ends of the stringer; then put the skin close to the stringer, and press the skin with the strip-shaped pressure plates on both sides. After the skin is installed, the hole making and riveting work are carried out to assemble the stringer and the skin as a whole. In addition, the tool nee...
